MAGAZINE TACK-HAMMER.

SPECIFICATION forming part of Letters Patent No. 668,836, dated February26, 1901.

Application filed March 21,1899- Serial No. 710.002. (No model.)

To all whom, it ntay concern:

Be it known that LGEoRcn ERNEST HAszIN- GER, a citizen of the UnitedStates, residing at Vicksburg, in the county of Warren and State ofMississippi, have in vented certain new and useful Improvements inMagazine 'IaclcHainmers; and Ido hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to magazinehamlners adapted to use tacks orsmallnails,brads, &c., and is in the nature of an improvement upon theconstruction disclosed in Letters Patent No. 609,672, granted to me onor about August 23, 1898.

One of the objects of the presentinvention is to do away with the lostmotion from the engagement between the screw or spiral and theoperating-rod and lip described in said patent.

Another object of the invention is to provide a reliable lock forsecuring the tack carrier or feeder in position to successively receivethe tacks or nails one at a time, the construction at the same timepreventing any tendency of the carrier or feeder to rebound.

By the improvements hereinafter described a magazine-hammer is providedwhich presents a neater appearance, which operates with greatersmoothness, and which is stronger and more durable and in many respectsmore satisfactory.

The detailed objects and advantages of the invention will appear morefully in the course of the subjoined description.

The invention consists in a magazine-hamm erembodying certain novelfeatures and details of construction and arrangement of parts, ashereinafter fully described, illustrated in the drawings, andincorporated in the claims hereto appended.

Fig.13 is a similar view showing the rear portion of the handle, 850.,omitted from Fig. 12.

Similar n u merals of reference designate corresponding parts in all thefigures of the drawings.

Referring to the drawings, 1 designates the handle of the improvedmagazine-hammer, the said handle in its preferred form and as shown inFigs. 1 to 6, inclusive, being constructed of metal and in the form of ahollow tube oblong in cross-section, as shown in Fig. 6, and cut away onits upper side, as shown at 2, the edges being rolled, as indicated at3, for the purpose of reinforcing the stock or handle of the hammer andimpartinga greater strength thereto. Connectedto the end of handle 1 isa head 4, having a poll 5 for driving purposes, and also anoppositely-extending portion 6 of the poll, which is provided with aslot 7, through which the tacks or nails pass to the carrier or feeder,(indicated at 8.) Extending longitudinally through the handle is achannel-plate 9, having a closed bottom,

as shown, and provided inits upper side with a slot 10, through whichthe shanks of the tacks move, the heads of the tacks resting on thebottom of the channel-plate and the points of the tacks extending upwardthrough the slot 10. The channel-plate 9 extends also through the slot 7and terminates flush with the outer surface of the head, with theexception that one of the flanges on one side of the slot 10 isextended, as shown at 11, so as to cooperate with thelaterally-extending and upwardly-inclined lip 12 of the tack-clamp 13,hereinafter particularly referred to.

The tack carrier or feeder is arranged outside of the head 4, as clearlyshown in Figs. 1 and 2, for example, and is pivotally mounted at thepoint 14, whereit has a rearwardlyextending nut or hollow spindle 15,which passes through and is journaled in a cylindrical opening 16 in thepoll 5 and is held therein by means of a circumferential flange 17 atits rear end, which bears against the inner surface of the poll.Extending longitudinally through the nut or spindle is a round bore 18with a rectangular entrance, in which fits an actuating-spiral 19, whichis preferably formed of a piece of flat steel or other metal, which istwisted to form the spiral 19. The spiral 19 extends longitudinally ofthe hammer or in parallel relation to the handle and constitutes thefree end of an L-shaped bracket or arm20, which is secured to a stem orrod 21, which extends longitudinally irough the hollow handle 1 beneaththe raceway or channel-plate 9, as shown in Fig. 3. At its rear endthestem 21 is bent laterally and downward to form a finger-grip 22,which operates in a slot 23 in the casing and which is in convenientposition to be grasped by one of the fingers of the operator Whilemanipulating the hammer, the grip 22 being drawn rearwardly foractuating the tackcarrier. Intermediate its ends the stem 21 passesthrough suitable bearings 24 and is also encircled by a coiled expansivespring 25, which operates to thrust the stem 21 forward or in thedirection of the hammerhead, said spring being seated at one end againstone of the bearings 24 and engaging at its opposite end a collar or pin26 on the stem 21. The stem 21 is extended beyond the arm and passesthrough an opening 27 in the ham mer-head 4 and intermittently enters asocket 28 in the inner face of the tack-carrier 8, so as to lock saidcarrier in position to receive the tacks.

From the above description it will be seen that as the finger-grip 22 isdrawn back and the stem 21 slipped rearward its extremity will move outof engagement with the socket 28, thereby unlocking or freeing thecarrier or feeder 8. Just after the stem moves out of the socket 28 thespiral 19 cooperates with the hollow spindle 15 and begins to rotate thecarrier or feeder 8. The cooperation of the spiral and the nut or hollowspindle is sufficient to turn or oscillate the carrier or feeder 8through a half-revolution, thereby enabling the carrier or feeder toreceive the tack point upward and deliver it point downward. In

order to limit the extremes of movement of the oscillating carrier orfeeder 8, two stops 29 are provided, (see Fig. 11,) one of whichregulates the upward position of the carrier and the other the downwardposition thereof.

Just as the feeder 8 strikes the upper stop 29 the stem 21 looks thecarrier and prevents it from rebounding, thereby holding it in positionto receive the next tack.

By reference to Figs. 7 and 10 it will be seen that the carrier 8 isprovided at its free end with a recess 30 to receive the tacks. The saidrecess extends to the extremityofthe carrier and is closed by means ofacap 31, which is bent to extend around and against the outer face of thecarrier 8, as shown at 32, where it is secured by a removable fastener33, thereby enabling the cap to be detached for inserting a number ofinterchangeable clamps 13 for different-sized tacks. The cap 31 isprovided with a notch 34, through which the points of the tacks project,and the tackclamp 13 is also provided with a notch 35-folthe samepurpose. By reference to Fig. 3 it will be seen that the clamp 13 isheld downward by a spring 36, secured at its lower end by a wedge orblock 37, the free end of the spring bearing against the recurved outeredge 38 of the clamp, said parts being arranged in a suit-able recess inthe carrier. A spring-clasp 39 may be applied to the free end of thecarrier 8 for the purpose of clasping or holding a bill-poster or otherarticle previous to driving a tack therein when operating at aconsiderable distance above the head of the operator. After driving thetack and as the carrier or feeder 8 swings backward to its normalposition the lip 12 of the tack-clamp strikes against the extension 11,hereinabove described, and serves to lift the clamp-plate, therebyenabling the tack to pass from the raceway or channel-plate into thenotch 35. As the carrier 8 is moved laterally for the purpose of feedingthe tack the clamp-plate 13 passes out of engagement with the extension11 and immediately the clam p-plate is thrust downward by the mechanismhereinabove described, thus clamping the head of the tack between it andthe bottom of the recess 30, leaving the point of the tack projectingbeyond the cap-plate 31, so that it may be driven.

A spring-stop 40 is applied to the handle near the poll and consists ofa piece of springwire secured at one end, as indicated at 41, to thehandle and bent near its free end to form a transverse stop 42, whichprojects across the discharge end of the raceway or channel-plate, asclearly shown in Fig. 4. After forming the stop 42 the wire is bent toform a longitudinally-extending lip 43, which lies in the path of thepivoted carrier 8. As the carrier or feeder 8 is moved upward to receivea tack it strikes against the projecting lip 43 of the spring-stop andmoves the transverse stop 42 away from the raceway and out of the pathof the tacks, thereby enabling a tack to be fed by gravity into therecess in the carrier. As the carrier Sis started downward thespring-stop 40 is released and the part 42 moves across the raceway andcuts off the other tacks.

In rear of the spring-stop 40 is a checkspring 44, secured at one end,as shown at 15, and extending obliquely across the raceway, where itsfree end is bent back at an acute angle to form a transverse stop orcheck 16. The check-spring 44 is quite light and enables the tacks byreason of their weight to deflect it, so as to pass beyond theeXtremit-y46 thereof. hen the head of the hammer is raised for driving atack, the part 46 prevents the farihermost tacks from receding.

At the rear end of the handle is a cut-off spring 47, fastened at oneend, with the free end passing through an opening +18 in the han dle, asshown in Fig. 2, and extending across the raceway or channel-plate, asshown in Fig. 6, thereby preventing the tack from falling off of therear end of the handle. In connection with the handle 1 I employ afiller or loading-fork 49, which is also hollow or tnbular and providedwith tapering forward ends 50, which are also flaring or deflectedlaterally to form a mouth 51, into which the tacks are easily inserted,the rear end of the filler being closed to prevent the escape of thetacks. In loading the filler the latter is inverted, as shown in Fig. 9,and the tacks are passed in through the flaring mouth 51 pointsdownward, with the heads resting on the edges 52 of the raceway, theheads of the tacks passing beneath the bottom 53 of the filler orloading-fork. After the filler 49 has been loaded the lips are insertedin the rear end of the handle, where one of said lips is engaged by theoperator with the end of the cut-off spring for pushing said cut-off toone side and leaving the raceway free, so that the tacks may slide bygravityfrom the filler into the raceway in the handle. Upon withdrawingthe filler the cut-off automatically moves across the raceway andprevents the escape of the tacks contained in the handle.

In Figs. 12 and 13 I have shown the manner of applying a wooden handle54 to the hammer, the head 4 being mounted directly on the end of saidhandle. The channelplate forming the raceway is made quite shallow,being shown at 55 and being provided with lips or ears 56, which extenddown upon the sides of the handle and are secured thereto by suitablefastenings 57. The channelplate 55 is provided at its rear end with acut-off spring 58, similar to that of 47, hereinabove described. On theunder side the handle 5a is provided with eyes 57, through which thestem 21 passes. Instead of making the arm 20 and spiral 19 separatelyand attaching them to the stem 21, by reference to Fig. 12 it will beseen that the spiral 19 is formed integral with the stem 21, and saidstem is also extended laterally, as indicated at 59, and then laterally,as at 60, to form a locking-finger similar to that of 21, abovedescribed, which enters the socket 28in the tack carrier or feeder.Instead of placing the part 60in the center of the head it is in somecases preferable to arrange the same a little to one side, so as not toweaken the handle 54, in which event instead of engaging acentrallylocated socket 28 in the carrier 8 the extremity of the part 60will engage the side face of the carrier 8 or else bereceived in a notchin the side of the carrier 8, as shown in Fig. 11.

By means of the construction described thereis no lost motion-anobjection found in the construction described in my formerpatentreferred to. The lost motion would cause the carrier to stand ormove out from the raceway, thereby leaving an open space and at timesenabling two tacks instead of one to find their wayout of the raceway atthe same time. In using the ham merit is best to strike a rapid blow,thus causing the tacks to be thrown forward by centrifugal force, afterwhich they will be prevented from moving backward by means of thecheck-spring 4A. The plug in the end of the handle is to accommodate thetrigger-lock and rivets and to give a rigid connection.

It will of course be understood that a han dle of any desired orrequired length may be employed and that the device as a whole may beadapted to different-sized tacks, nails, or other fastenings by removingthe cap-plate 31 and substituting clamp-plates 13 of different sizes.These and other changes in the form, proportion, and minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention.

Having thus described the invention, what I claim as new, and desire tosecure by Letters Patent, is-

1.
